The sum of three consecutive even integers is –78. What are the integers? Describe how you would use the strategy of writing an

equation to solve the given problem. Which of the following did you include in your description? Check all of the boxes that apply. Let x = the smallest even integer, x + 2 = the next even integer, and x + 4 = the largest even integer. Write the equation x + x + 2 + x + 4 = –78. Simplify the equation as 3x + 6 = –78. Solve the equation by subtracting 6 and dividing by 3 on both sides of the equation. Check that the sum of the integers –28, –26, and –24 is –78.

Which is the simplified form of the expression (6-4)-9
Veseljchak [2.6K]

I'll give you a hint. <u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtracting.</em></u>

First you had to calculate with parenthesis first.

(6-4)=2-9

Then you add and subtract from left to right.

2-9=-7

Final answer \boxed{=-7}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

A new battery is expected to have a storage capacity of 60 ampere-hour (A h). A sample is tested, resulting in a 2-side confiden
antoniya [11.8K]

Answer:

Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %    

Step-by-step explanation:

We are given the following in the question:

Mean storage capacity = 60 ampere-hour

95% confidence interval =

63\leq \mu \leq 72

Thus, the correct answer based on the confidence interval is

Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %

Since it is a two sided test we test whether the mean storage capacity is 60 Ah or different than 60 Ah

Thus, the battery storage is different from 60 Ah because the mean storage capacity does not lie in the 95% confidence interval.

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
Serggg [28]

Answer:

The last one (x,y)->(x+3,y+5)

Step-by-step explanation:

Whenever you move the x coordinate it’s the opposite, for example translated 3 units the the left is +3 and translated 3 units to the right is -3.

Whenever you move the y coordinate it’s normal so up 5 units means +5 and down means -5.
